Research adds to the growing body of evidence that even moderate drinking can be harmful. A drink is defined as 14 g of pure alcohol – a reliable way to know how much alcohol has been consumed [29-30]. Table 2 and Table 3 show the drinking level of alcohol and the associated risk in males and females. “We don’t know whether moderate drinking is truly cardioprotective or if it is merely a marker of a healthy lifestyle,” Messerli said. In the general population, some studies suggest that alcohol consumption might enhance heart rate variability or keep plaque from building up inside arteries, but the mechanism is still not clear, He said.

It can cause symptoms like anxiety, shaking, nausea, sweating and trouble sleeping. Someone who is detoxing from alcohol usually has elevated blood pressure. This problem is worse in people who have had more severe drinking or who have been drinking for longer time periods.

As the professional home for the entire cardiovascular care team, the mission of the College and its more than 52,000 members is to transform cardiovascular care and to improve heart health. The ACC bestows credentials upon cardiovascular professionals who meet stringent qualifications and leads in the formation of health policy, standards and guidelines. Compared with those who never drank, moderate drinkers were 53 percent more likely to have stage 1 hypertension and twice as likely to have stage 2 hypertension. The pattern among heavy drinkers was even more pronounced; relative to those who never drank, heavy drinkers were 69 percent more likely to have stage 1 hypertension and 2.4 times as likely to have stage 2 hypertension. Overall, the average blood pressure was about 109/67 mm Hg among never-drinkers, 128/79 mm Hg among moderate drinkers and 153/82 mm Hg among heavy drinkers. Alcohol’s impact on blood pressure could stem from a variety of factors, according to researchers. Because alcohol increases appetite and is, itself, very energy-dense, drinking often leads to greater caloric intake overall.

Alcohol — especially when consumed excessively — can raise blood pressure over time, cause irregular heartbeats , and weaken the heart so it is unable to pump effectively. In addition, alcohol can raise your triglycerides, which are a type of fat in the blood. And if you’re taking medication to treat high blood pressure, be aware that alcohol may hinder the medication’s effectiveness and also worsen side effects. A drug once used to treat high blood pressure can help alcoholics with withdrawal symptoms reduce or eliminate their drinking, Yale University researchers report Nov. 19 in the American Journal of Psychiatry. Light to moderate drinking may have some protective benefits for your heart, according to a 2017 study published in the Journal of the American College of Cardiology. Currently, there is little data on the association between alcohol use and hypertension. Considering the high prevalence of both alcohol use and hypertension, as well as hypertension’s possible association with other cardiovascular risk factors, a link between the two is likely.

Can Damage From Excessive Drinking Be Reversed?

ARBs lower blood pressure by blocking the actions of a hormone called angiotensin II that’s naturally produced by the body . These prescription drugs are used in the treatment of hypertension because they prevent this squeezing . Losartan is a prescription medication used to treat high blood pressure. It belongs to alcohol and high blood pressure a drug class called angiotensin receptor blockers that also includes the medications valsartan and irbesartan. ARBs are generally used to treat high blood pressure, though losartan is approved by the U.S. Food and Drug Administration to treat high blood pressure , risk of stroke, and kidney problems from diabetes .

Many of these salt substitutes use potassium chloride, which should be avoided if you need to limit potassium . Your healthcare provider may measure the levels of potassium in your blood to decide if you need to limit your potassium intake. Since high blood levels of potassium can be dangerous, you may need to avoid high-potassium foods when taking ARBs.


All authors, except for DD, GG, JM, JAAP, and KDS, participated at the “Screening and intervention for harmful alcohol use as a tool to improve the management of hypertension in primary care” conference in Barcelona. The discussions during this conference were condensed and compiled by JR, which resulted in the first draft of the manuscript. DD, GG, JM, JAAP, and KDS contributed critical content to this manuscript. This does not even include the effect of reduced alcohol use on other disease categories such as AUDs or cancer. For the latter disease category, the effects would only be seen after decades due to the long time lag . For the other disease categories, lag times are short , and the vast majority of deaths will be covered, including liver cirrhosis deaths, where interventions have shown immediate effects . We based our recommendations on the GRADE approach, which rates the quality of evidence for a particular outcome across studies and does not rate the quality of individual studies .

After the liver filters most toxins out of the body, the kidneys are responsible for removing much of what is left. However, if the liver does not filter enough alcohol out of the body, it will reach the kidneys and damage that organ’s ability to process toxins. The kidneys are also responsible for keeping enough water in the body; when poisoned by too much alcohol, the kidneys are not able to prevent dehydration.

Frozen pizza can be incredibly unhealthy for people with high blood pressure. One serving of a frozen pizza can contain 700 milligrams of sodium or more depending on the toppings. Tomato products with added salt are problematic for people with high blood pressure. Most canned pasta sauces and tomato juices typically have anywhere from 100 to 300 milligrams of sodium per serving, which can be almost 10% of the daily recommendation. As an alternative, you can easily find low or reduced-sodium versions of canned tomato products or use fresh tomatoes, which are more delicious anyway.

  • Exercise increases the utilization of oxygen in the body and up-regulate the antioxidant defense system in the cardiovascular system[97-100].
  • Recent studies have shown the beneficial role of physical training in the control of blood pressure in humans and experimental animals.
  • Exercise training also generates NO in the cardiovascular system by induction of nitric oxide synthase.
  • There is a physiological basis for effect of physical conditioning on chronic alcohol-induced hypertension in a rat model.
  • Another non-pharmacological prevention and treatment of alcohol-induced hypertension is physical conditioning or exercise training.
  • Although the evidence of direct nephrotoxicity is lacking, many mechanisms of kidney injury associated with alcohol consumption have been proposed, including oxidative stress and renal disease caused by other systemic conditions .

In small amounts, it has been shown to lower blood pressure by 2 to 4 mm Hg in women. Most experts agree, though, that does not show a significant enough drop to advise drinking for an entire population.Learn more about alcohol and blood pressure. Heavy drinkers who cut back to moderate drinking can lower their top number in a blood pressure reading by about 5.5 millimeters of mercury and their bottom number Addiction by about 4 mm Hg. To understand how much alcohol is too much and how cutting back can lower your blood pressure, it may be helpful to know the definitions of excessive drinking. Moderate alcohol consumption while taking losartan is generally considered safe, but alcohol may make the side effects of losartan worse. This combination could potentially cause drowsiness, dizziness, and even fainting.

Central Nervous System In Alcohol

People who drink small amounts may have lower blood pressure in some cases, although chronic drinking is generally always associated with high blood pressure. All of the four recommendations have been chosen as measurable, achievable, and realistic for implementation in primary healthcare. Obviously, as with all recommendations, implementations should be carefully evaluated. While we have laid out the economic arguments for implementing the recommendations, these are currently based on assumptions and different modelling approaches.

That being said, alcohol also has the potential to harm your heart in other ways. Binge drinking can raise a person’s blood alcohol to dangerous levels. This can cause a sudden drop in kidney function known as “acute kidney injury.” When this happens, dialysis is needed until a person’s kidney function returns to normal.

Finding that link could prove to be vitally important as public health measures aimed at alcohol abuse could impact hypertension rates, and subsequently cardiovascular morbidity and mortality. But even these small amounts of alcohol have been associated with an increased risk for high blood pressure, he said. If anything, beneficial effects of alcohol should be even more pronounced for people without high blood pressure, said Dr. Franz H. Messerli a cardiology expert at the Icahn School of Medicine at Mount Sinai in New York. Observational studies only include data on what people do in their lives and what happens to them, and can’t say for sure that one action, like drinking alcohol, causes a particular result. The American College of Cardiology envisions a world where innovation and knowledge optimize cardiovascular care and outcomes.

This can cause health consequences ranging from pain to behavioral disturbances to life-threatening cancers. The researchers conclude alcohol consumption alcohol and high blood pressure should be considered as a relevant age-dependent risk factor, and say it could have relevance to studies of younger patients with stroke.

Rehm J, Gmel G, Sierra C, Gual A. Reduction of mortality following better detection of hypertension and alcohol problems in primary health care in Spain. The potential effect of the alcohol and high blood pressure interventions on reducing mortality would be sizeable. Drinking plenty of water while drinking alcohol can help prevent dehydration and reduce alcohol-induced feelings of hunger.

As part of a comprehensive treatment plan for alcohol use disorders, group therapy, individual counseling, family counseling, support group meetings, wellness activities, and medication treatments may be included. The bottom line, Klatsky says, is you can’t make a drinking rule that applies broadly for people with high blood pressure. If you’ve been told by your healthcare provider to avoid table salt as a means to control your blood pressure, you may have come across salt substitutes in your efforts to make your food a little tastier.

Acute kidney injury usually goes away in time, but in some cases, it can lead to lasting kidney damage. The rate of blood flow to your kidneys is usually kept at a certain level, so that your kidneys can filter your blood well.
